Tex. Occupations Code § 303.011

(a) In evaluating a nurse's conduct, the nursing peer review committee shall review the evidence to determine the extent to which a deficiency in care by the nurse was the result of deficiencies in the nurse's judgment, knowledge, training, or skill rather than other factors beyond the nurse's control. A determination that a deficiency in care is attributable to a nurse must be based on the extent to which the nurse's conduct was the result of a deficiency in the nurse's judgment, knowledge, training, or skill.

(b) The nursing peer review committee shall report a deficiency in care that the committee determines was the result of a factor beyond the nurse's control to a patient safety committee for evaluation. The patient safety committee shall evaluate the influence of the factors on the conduct of the nurse being evaluated and on the practice of other nurses within the entity that established the committee. The committee shall report its findings to the nursing peer review committee.
